With the advent of diffractive multifocal IOLs, precise centration of the lens has become paramount. In today’s discussion, Dr. Lisa B. Arbisser speaks with optics expert Dr. Jack T. Holladay about how to center an IOL and save patients from the waxy vision, glare, and loss of contrast often associated with higher-order aberrations. Should the lens be centered on the optical, visual, or pupillary center, or instead with Purkinje images? Doc Holladay has the answer.
